1. CARE OF THE MANUAL AND HOW TO CONSULT IT
Keep this manual and keep it in an accessible place near the equipment.
In the event that the manual is lost or is in unfavorable conditions ask the installer for a copy or directly
to the manufacturer, specifying the identication data of the product.
The proper functioning of the boiler depends, to a large extent, on the user knowing its operation and knowing at all
times what to do. In this manual you have an index on pages 4 and 5 so that you can easily nd the section to consult
to solve the questions and doubts that may arise.
When we read or consult this manual, we will consider that:
Special attention should be paid to texts written in “bold”
In some cases, capital letters and/or increased font size can be used to draw attention to the paragraph.
The text in “italics”, is used when we mention other paragraphs of this manual, or for further clarications.
In some cases, two or more of the above resources could even be combined. This would be the case when we refer
to the reading of other chapters to complement or consult information:

4. FUEL
The FERLUX pellet boiler has been designed to burn wood pellets that meet the requirements established
in the UNE-EN ISO 17225:2014 Solid Biofuels Standard and in the ÖNORM M 7135 standard.
4.1 WHAT IS PELLET?
The pellet is a combustible material that is manufactured by pressing dry natural sawdust, it is easy to be compacted and
lignin itself is a binder, so no glue or other substance is needed. This process gives it a shiny appearance as if it were
varnished and makes it denser.
They are very small cylinders of a few millimeters in diameter, their humidity level is very low, and they also require little
storage space (to produce the same heat, the stored pellet occupies about three times less in volume than rewood).
4.2 PELLET CHARACTERISTICS
In the market there are several types of pellets which change according to the quality, characteristics of elaboration and
types of wood used.
FERLUX recommends burning wood pellets with DIN plus certicate (marked obtained according to Austrian standard
Önorm
M 7135) or ENplus (marked obtained according to UNE- EN ISO 17225-2:2004).
DINplus is a voluntary mark issued by an institute certifying that the pellet complies with the Austrian standard Önorm
M7135, one of the most restrictive standards on the market.
ENplus is also issued by an institute that certies that the pellet complies with the EN-14961-2 standard.
Main requirements of these regulations mentioned above:
Characteristics of the pellet according to DINplus and ENplus standard
Requirement Unit of measurement DINplus ENplus A1 ENplus A2
Diameter mm 4 ≤ D < 10 D06: 6 ±1
D08: 8 ± 1
Longitude mm ≤ 5 x D 3,15 ≤ L ≤ 40
Caloric value inferior MJ/kg (b.h) Q ≥ 18 (MJ/kg en b.s.) 16,5 ≤ Q ≤ 19 16,3 ≤ Q ≤ 19
Humidity % (b.h) ≤ 10
Ashes % (b.s) ≤ 0,5 ≤ 0,7 ≤ 1,5
A pellet certied under either of these two standards is the best guarantee for the proper functioning of the boiler
PELLET FERLUX.
If the pellet is not properly marked, the corresponding certicate should be requested.
PELLETS SHOULD NOT BE >45 mm AND ONLY 1% MAY BE LONGER THAN 40 mm.
In the event of an unidentied pellet or that due to various circumstances we consider that the characteristics have
been able to change, we can apply a series of criteria to know if it is suitable or not for its use, in which we will
follow the below tips:
• DO NOT USE pellets of dimensions other than those indicated in the table above.
• DO NOT USE pellets that show granules of colors not typical of wood, or excessively dark.
• DO NOT USE wet pellet.
• DO NOT USE pellets containing mixed sawdust powder, resins or chemicals, binders, or additives.

5. INSTALLATION INSTRUCTIONS
The installation of the FERLUX Hidromatic pellet boiler must be carried out only by qualied personnel, following the
manufacturer’s instructions and in accordance with all applicable rules and regulations in force. Otherwise, FERLUX
is not responsible in case of any accident.
We must choose the location of the boiler in such a way that the route to the vertical connection of the smoke outlet is as short
as possible.
Both in the device and in the smoke ducts we can have high temperatures, so you must follow the manufacturer’s
instructions to prevent possible res and dangerous situations. (See section 5.4 HOME FIRE PREVENTION.)
We must also consider the supply of air for combustion, as well as maintain adequate environmental conditions within the
enclosure. (See section 5.6 VENTILATION AND AIR INTAKE.)
THE USE OF FUELS SUCHAS CHIPS, CHOPPED FIREWOOD, BRANCHES IN GENERALIS PROHIBITED.
THE USE OF UNAUTHORIZED FUELS CAN HARM THE BOILER AND COMPROMISE ITS
PERFORMANCE LEADING TO THE CANCELLATION OF THE WARRANTY AND THE END OF THE
MANUFACTURER’S LIABILITY FOR THE PRODUCT.
The use of inadequate fuel causes:
• Accumulation of pellet in the burner.
• Dirt on the burner and smoke evacuation ducts.
• Bad combustion.
• Decreased boiler performance.
• Increased fuel consumption.
• The normal operation of the boiler is not guaranteed.
• Need to do more cleaning and maintenance in the boiler.
4.3 PELLET STORAGE
To ensure a smooth combustion, it is necessary to keep the pellets in a dry environment and not too cold. Wet and/or cold
pellets reduce fuel power and e󰀩ciency and require greater cleaning maintenance of the burners, body and chimney.
Take special care in the storage of the pellets, as well as in their displacement, avoiding the formation of sawdust
and that the bags break, since if this happened it could increase the humidity and the proportion of sawdust and the caloric
characteristics of the fuel would possible decrease
características calorícas del combustible.
THE USE OF PELLETS THAT DO NOT COMPLY WITH THE BEFORE MENTIONED REGULATIONS MAY
HARM THE BOILER AND COMPROMISE ITS PERFORMANCE, LEADING TO THE CANCELLATION OF
THE WARRANTY AND THE END OF THE MANUFACTURER’S RESPONSIBILITY FOR THE PRODUCT.
THE HIDROMATIC BOILER MUST ALWAYS BE INSTALLED BY AUTHORIZED PERSONNEL. ITS
IMPLEMENTATION WILL BE CARRIED OUT BY THE AUTHORIZED SAT OF FERLUX.

14
5.1 UNPACKING
To unpack the product, follow the instructions here below.
Packaging materials are non-toxic and non-harmful. Therefore, they do not require special disposal processes. It is the
responsibility of the end user, in accordance with the relevant laws, to store, dispose of and eventually recycle the packaging.
5.2 LOCATION
The boiler will be installed so that it is not necessary to move it from his position in cleaning operations, maintenance and
revisions, repairs, etc.
It is also necessary to have adequate access for cleaning the smoke connector and the chimney duct.

15
It is advisable to support it on a level, rm and re-resistant base, or baseboard.
For the correct combustion it is essential that the fuel is dry, so an adequate storage of it is recommended, which
will have to be at a safe distance from the boiler (at least 1 meter) or in a di󰀨erent room. In no case should it be stored
behind the boiler.
It will have a drain and sump connected to the drainage network.
The boiler should not be installed in rooms or areas where ammable or explosive products can be stored.
The installation of the boiler must ensure that the hydraulic circuit incorporates the necessary safety measures against the
increase in temperature and water pressure.
Any deciencies in the electrical installation must be repaired.
A DRAIN COCK WILL HAVE TO BE INSTALLED IN THE HEATING CIRCUIT, LOCATED AT THE LOWEST
POINT AND AS CLOSE AS POSSIBLE TO THE BOILER.

5.4.1 MEASURES TO CROSS ENCLOSURES
The smoke duct must cross one or more enclosures of the premises depending on where the device is going to
be installed.
The size of the holes that need to be opened depends on the diameter of the duct and the enclosure to be crossed.
Once the tube has passed the remaining space must be lled with insulation (rock wool, ceramic ber.)

Brick wall or ceiling 30 140
5.4 HOME FIRE PREVENTION
• The manufacturer’s instructions for both the installation and use of the boiler must be complied with, in addition to
all the corresponding safety regulations and regulations must also be complied with. Otherwise, FERLUX is not
responsible in the event of any accident.
• It is recommended to have out of the heat focus (at least 1.5m away) any combustible or ammable element such
as wooden beams, furniture, curtains, ammable liquids, etc. A protective layer of insulating and non-
combustible material should be placed in the heat focus area where ammable or heat-sensitive coatings are
in place.
• Periodic cleaning of the boiler and the smoke ducts must be carried out since the soot and other accumulated
combustion residues could enter into combustion.
• In the event of a chimney re, use the appropriate extinguishing systems to put out the re, or contact the reghters
for their intervention.
• If fumes occur during the operation of the boiler, ventilate the room, and check the tightness of the elements of the
same and the chimney. Once veried if the problem persists consult with the SAT to adopt a solution.
• In the case of having a ammable oor (parquet type, oating ooring.) or heat-sensitive soils, it is necessary
to place a protection that separates the stove from the ground. This protection should be of a re-resistant material
such as marble, sheet steel, tiles, etc. This material has to be able to resist without breaking due to the weight
of the boiler. It shall be at least 2 mm and shall be at least 150 mm from the boiler on the sides and rear and 300
mm from the front of the stove.
• Below is a table with the minimum safety distances that must always be guaranteed on a mandatory basis

5.5 FLUE OR CHIMNEY
We will use a ue or chimney to be able to remove the gases that are produced in the boiler during combustion to the
outside.
The responsibility for the works carried out for the ue is from the installer, so FERLUX recommends that the
installation be carried out by qualied personnel (who are in possession of the installer’s card), which will be
asked to perform the checks relating to the smoke duct, air intake, etc. In addition, all the safety regulations provided
for by the specic legislation in force in the country where it is installed must be respected.
5.5.1 GENERAL FUNDAMENTALS
For the installation of the ue, the following points must be considered:
• The smoke evacuation system must be unique for each boiler (smoke outlet evacuations in common
with other appliances are not allowed).
• The smoke evacuation route will always be as short as possible and always looking for maximum
verticality.
• The internal section of the smoke evacuation duct should be uniform and preferably circular. In the event
that we had a square or rectangular section, the edges should be rounded with a minimum radius of 20 mm,
the curves will be regular and without discontinuities, ensuring that the deviations of the path refarding the axis are
not greater than 45°.
• It is strictly forbidden to install valves or closures that may obstruct the passage of fumes.
• It is necessary to avoid horizontal sections of chimney, since this most likely will get it dirty and requires a
more frequent cleaning of the ducts, in the event that it is inevitable there will be a minimum of upward inclination
and “T” will be installed in the changes of direction to provide cleaning access without having to disassemble all
the installation. The installation must be carried out in such a way as to ensure regular cleaning without the need
to dismantle the entire ue.
• For the installation of the smoke duct, safety standards and minimum distances must be respected.

5.5.2 CALCULATION OF THE SMOKE OUTLET DUCT
For the layout of the chimney, we will consider the following indications:
• AISI 316 stainless steel tubes, varnished aluminized steel tubes of minimum thickness of
1.5 mm, porcelain tubes of minimum thickness 0.5 mm.
• Flexible tubes are allowed if they meet the specications set by the law (stainless steel with
smooth inner wall), the clamps must have a minimum length of 50 mm.
Below is a table in which you can nd the limitations for installation:
LIMITATIONS WITH DOUBLE WALL
TUBE Ø 120 mm
WITH DOUBLE WALL
TUBE Ø 150 mm
Horizontal sections with min. 5% 2 m 2 m
Minimum length (mandatory vertically) 2 m 2 m
Maximum length (with 2 90 ° bends) 5 m 7 m
The maximum length allowed for vertically installed duct has been calculated, with a maximum
of two 90 ° bends and practically no horizontal section (only to cross the wall if necessary).
If the installation is di󰀨erent from the one indicated above, the “equivalent head loss” of the
installation must be calculated.
The “equivalent pressure loss” of an installation is the result of the sum of the total meters of the installation, plus
the additional losses that are derived from the following table:
TYPE OF LAYOUT OR ACCESSORY LENGTH TO SUBTRACT FROM THE TOTAL
ALLOWED
90° curve 1 m
Horizontal span 45° curve 2 m
Accessory in "T" 1 m
Diagonal section 0,5 m
45° curve 0,5 m
The sum of these losses must be less than or equal to the maximum allowable length indicated in the table of limitations.
If this is not fullled, the diameter of the smoke duct to be installed should be increased:
LOSS OF LOAD EQUIVALENT ≤ MAXIMUM ALLOWABLE LENGTH

19
5.5.3 INSTALLATION IN TRADITIONAL TYPE FIREPLACES (see)
When you want to take advantage of an existing chimney it is necessary to make a control check on the tightness of
it, in the event that it was not watertight it could be the case of a positive depression with respect to the atmospheric
that could lter and invade inhabited environments. It is advised if it is not completely watertight that it should be re-
intubated.
If the section of the chimney is excessively large, it is contemplated to pipe it with a maximum diameter of Ø150
mm, and is also advisable to insulate it.
It is MANDATORY to carry out a thorough cleaning of the smoke outlet, to reduce the risk of re in the gas outlet
5.5.4 OUTER SECTION OF CHIMNEY (see FIG. 21)
To use the section of the exterior chimney, the following requirements must be met:
• The installation that goes to the outside must be with insulated tubes with double stainless steel wall and xed to
the building.
• This external conduit must have a register for periodic maintenance.
• The chimney must go up to the summit, and the requirements of section 5.3 must be met.

5.5.5 SMOKE OUTLET TERMINATION
The smoke outlet always has to end vertically and will have in its upper part the device that we call auction and that
must comply with the following:
• It must have a useful internal section equivalent to that of the evacuation tubes.
• The useful output section must be at least twice as many as the evacuation tubes.
• The auction should prevent rain, snow or foreign bodies from entering the chimney.
• In addition, the nish must be anti-wind and overcome the ridge to guarantee the dispersion and dilution of
the combustion products.
• It is completely forbidden to install hats or deectors for horizontal output, like
• all those used for gas boilers, as they can cause problems in combustion.
It is totally forbidden to cover the chimney with anti-bird nets, meshes or similar.

5.6 VENTILATION AND AIR INTAKE
• In the cabin where the boiler is installed, we must ensure that we will have at all times the necessary air to guarantee
a good combustion, in addition to optimal conditions of habitability within the enclosure.
• The outside air intake whenever possible should be connected to the room where the stove is installed. We must
make sure that the entrance of outside air cannot be obstructed.
• If in the room where the stove is going to be installed we do not have enough natural ventilation, it will be essential
to practice some opening, which guarantees us the necessary air from the outside (at least it should have a section
of 100 cm2).
• Air can also be obtained from an adjacent room, provided that such ow can easily reach through
of permanent openings, which cannot be closed and which communicate with the outside.
• The premises cannot be used as a garage, material warehouse or activities with a risk of re.
• The ventilation of the premises must satisfy the minimum ow required according to specic regulations and the ow
rate of maximum intake air of the apparatus.
• Collective ventilation ducts are prohibited.
• The air intake must be placed respecting at least 500 mm both horizontally and vertically from the smoke outlet.
• The air intake for combustion cannot be connected to any air installation, nor is it recommended to take air directly
from the outlet on the wall.
In the case in which there is no other way than to connect the primary air intake directly to the outlet practiced on the
wall, it should be of a larger diameter, in order to avoid all the problems caused by the lack of primary air intake. The
air intake practiced on the wall will not have any type of mosquito net or similar mesh since this decreases the entry of
primary air to the device with the consequences that this implies in the ignition and operation of the same (Er41, see
Chapter 9 of this manual).
The extension is to be made as follows:
■When the primary air intake in the equipment is Ø 60 mm we must expand to Ø 110 mm
IN THE CASE OF CHANNELING, AVOID ANY KIND OF ELBOW
IT IS TOTALLY FORBIDDEN THE INSTALLATION OF A COAXIAL TUBE IN
ANY FERLUX EQUIPMENTS.
SINCE COMPLIANCE WITH THE BEFORE MENTIONED IS BEYOND OUR CONTROL,
FERLUX WILL NOT BE RESPONSIBLE FOR ANY INCIDENT CAUSED BY THE BREACH
OF THE MENTIONED POINTS.
